Title: Tape-holding cartridge for record playback tapes of the endless band type
IPC: G11B23/06
Filed: 1961-10-19
Abstract: 914,565. Endless record-tape magazines. CAILLIOT, S. Oct. 19, 1961 [Oct. 21, 1960; Sept. 28, 1961], No. 37543/61. Class 40 (2). An endless tape magazine for magnetic or other tape and adapted to be placed over a gramophone turntable for drive purposes as generally described in Specification 775,532 has a number of rollers 19-21 of varying diameters driven at equal angular speeds by discs 22a to support and drive the coiled tape (of which only four turns are indicated in Fig. 2). A member 33, mounted to the turntable, provides a tape-capstan surface 47 and supports a tyre 33a driving the rollers 22a. The placement of the smaller-diameter, braking rollers 21 and the larger-diameter, accelerating roller 20 with respect to the sprung guide-roller 27 at the inner take-off point of the tape coil and the tape-pulley arrangement 12, driven by a standard-diameter roller 19a together prevent the stored coil becoming elliptical with resulting increased friction. A control member 3, when actuated clockwise, applies a pinch-roller 23 to the capstan, releases a tape-clamp 31, which presses the coil against the lid 1 and unlatches means 39 holding the member 33 against the body 35 and further means engaging pins 53 to prevent relative rotation during transport. The tape, where magnetic, may be double-sided and spliced into a Mobius loop to double the playing time and the head 6, which may be double-track for stereophonic use, may be movable to engage alternative tracks on the tape. A lead 7, connects the head to a socket which may be covered by the member 3 and from which connection may be made to record/playback amplifiers &c. The cassette may also be used with conventional tape-recorders (Fig. 5, not shown).

Title: Launching rack for a sam guided missile
IPC: F41F3/04
Filed: 1970-08-04
Abstract: 1501079 Launching rack VEREINGTE FLUGTECHNISCHE WERKE - FOKKER GmbH 4 Aug 1970 [11 Sept 1969] 37686/70 Heading F3C A launching rack for a SAM guided missile includes a device which imparts a rotational impulse to the missile about a transverse axis during its acceleration along the rack. In the embodiment illustrated, the launching rack 2 carries three guide rails, the front rail 3 being rigidly mounted and the two rear rails 4 adapted to turn about a transverse pin. The missile 1 has three points of suspension 7, 8 which are constructed as rollers or sliding shoes. The resultant movement of the missile can be regarded as a translation in the firing direction, which is defined by the firing angle #, and as a rotation about the transverse axis extending through the rear suspension points 8. The rotation is produced by the inclined guide rails 4, which impart to the suspension points 8 of the missile 1 a force component perpendicular to the longitudinal axis of the missile. The missile 1 thus receives on the launching rack 2 a rotational impulse which, at a particular acceleration, is dependent upon the angle of inclination # of the guide rails 4, upon the distance R between the front and rear suspension points 7, 8, and upon the moment of inertia of the missile about its transverse axis. The rotational impulse about this axis produces a change of course of the missile in the low speed range and this results in low mechanical stressing of the missile structure owing to small acceleration values transverse to the longitudinal axis of the missile. The reproducibility of a particular flight path is very good, since the distance R and the inclination # can be accurately adjusted. The early change of course of the missile with the resultant considerable curvature at the beginning of the trajectory enables the missile to fly over obstacles such as prominent features of the terrain, or vegetation or buildings employed for the purpose of camouflage which would be situated in the flight path using a line-of-sight launching method, in particular when firing at low-flying aircraft.

Patent GB-922085-A (GB)
Title: Improvements in the production of film and tubing of organic thermoplastic material
IPC: B29C48/10
Filed: 1959-11-10
Abstract: Tubular films are continuously produced by extruding an organic polymeric thermoplastic material through an annular extrusion orifice at a temperature above the first order phase transition temperature of the material to form seamless tubing, withdrawing the tubing from the orifice at a rate greater than the rate of extrusion, cooling the tubing to a temperature between the second order phase transition temperature of the tubing material and a temperature 20 DEG C. higher than the latter, re-heating the cooled tubing to a temperature more than 20 DEG C. above the second order phase transition temperature and within a temperature range at which the tubing can be molecularly oriented by a stretching operation, introducing and maintaining a gas within the interior of the tubing under a pressure sufficient to stretch the reheated tubing to a diameter greater than its extrusion diameter, and cooling the resultant tubular film.  The process is particularly applicable to the production of film from rigid styrene polymer and rigid vinyl polymers, including polymers of para-chloro-styrene, alphamethyl styrene, para-ethylstyrene and the vinyl naphthalenes, copolymers of styrene with acrylic acid esters such as butyl methacrylate, hexyl methacrylate and 2-ethyl hexyl acrylate, or with nitriles such as acrylonitrile, polyvinyl chloride and vinyl chloride-vinyl acetate copolymers.  The process is also applicable, however, to the production of films of cellulose acetate, polyethylene and polypropylene.  In an example, a rigid polystyrene having a tensile modulus of 400,000 p.s.i., a molecular weight of 52,000, and a second order phase transition temperature of 82 DEG C. is extruded at 183 DEG C. to form tubing having a diameter of 2 inches and a wall thickness of 20 mils.  The tubing is withdrawn vertically upwards from the extrusion die first through a zone in which it is cooled to 100 DEG C. by means of air directed on to its exterior from a cooling ring encircling the tubing, and then through a zone in which it is re-heated to 133 DEG C. by means of 8 infra-red lamps arranged in circular fashion around the extruded tubing.  From the heating zone the tubing passes to two co-operating pinch rolls which withdraw the tubing from the die at ten times the extrusion rate. The re-heated tubing is inflated by means of air to about eight times the extrusion diameter.  Specification 922,083 is referred to.

Abstract: 1,236,996. Calendar clocks. NAUCHNOISSLEDOVATELSKY INSTITUT CHASOVOI PROMYSHLENNOSTI NIICHASPROM. Aug. 9, 1968, No.38079/68. Heading G3T. A clock calendar mechanism for successively displaying the days of the month and the days of the week comprises a toothed date ring 1 for the display of numbers corresponding to the days of the month, a ratchet wheel 6 for the display of the week days and a lever 11 having teeth 17, 18, the tooth 18 being engaged by the pin 21 of a gear-wheel 20 to jointly reset the day of the month and the week day indications whilst the tooth 17 is engaged to reset the day of the month indication alone. The gear-wheel 20 rotates one revolution in twenty four hours and towards the end of a day the pin 21 engages the lever 11 to advance it along guides 22, 23 so that projections 14, 15 are moved away from the teeth of the date ring and the ratchet wheel. Further rotation of the pin causes it to engage the tooth 18 thereby rotating the lever in a counterclockwise direction and positioning the projections 14, 15 between the next pair of teeth 2 2 , 2 3  and 7 2 , 7 3  respectively. As the pin leaves the tooth 18 a spring 12 rotates the lever in a clockwise direction thus rotating the ratchet wheel and the date ring. The ratchet wheel carries a disc (not shown) displaying the names of the week days. To reset the ratchet wheel and the date ring simultaneously the hands of the clock are set to indicate midnight and then rotated backwards through about five hours so that the pin 21 is in engagement with the tooth 18. Clockwise rotation of the hands then resets both the day and date indications. To reset the date number alone, the hands are rotated counter-clockwisethrough about three hours from the midnight position, the pin 21 engaging the lever 11 to lift the projection 14 above the teeth 2 whilst the projection 15 remains between the same ratchet wheel teeth since the height of these teeth is greater than that of the date ring teeth. The pin then engages the leading edge of the tooth 17 so that subsequent clockwise rotation of the hands only changes the date number indication. The date ring and the ratchet wheel are provided with spring- biased detents 3 and 8 respectively.

Title: Manufacture of magnesium phosphate
IPC: C05B9/00
Filed: 1963-10-01
Abstract: In a process for the manufacture of anhydrous magnesium phosphate, possibly in mixture with calcium sulphate, from rock phosphate, the rock phosphate is heated in a reaction mixture which contains magnesium sulphate and a salt which lowers the fusion temperature of magnesium sulphate, to a temperature at which the fusible ingredients of the reaction mixture are partially or fully fused while the phosphates remain solid, thereby to produce a partial fusion of the reaction mixture, and a product containing anhydrous magnesium phosphate is recovered from the reaction mixture. "Fusible ingredients" are those which fully liquefy and also those which merely sinter under the reaction conditions.  The process may be carried out by melting or sintering of the salts other than orthophosphates present at any time, i.e. tertiary calcium orthophosphate at the beginning and increasing proportions of tertiary magnesium or mixed calcium-magnesium orthophosphates.  The magnesium salt may be magnesium sulphate as such or another salt, e.g. the chloride together with an alkali metal sulphate or chloride as the fusion-temperature lowering component, or a naturally occurring double salt or salt mixture containing magnesium sulphate can be used.  The rock phosphate and fusible ingredients may be fed, together or separately and continuously or in batches into a bath of molten salt from which magnesium phosphate and possibly calcium sulphate are withdrawn.  Temperatures of 600 DEG  C. to 300 DEG  C. are suitable.  Some CaSO4 may be removed from the product when the water-soluble ingredients of the reaction mixture are washed out.  In Example (1) the reaction mixture comprises Florida phosphate (tertiary calcium phosphate, calcium fluoride and calcium carbonate) and astrakanite (MgSO4.Na2SO4). In other examples Morocco rock phosphate is heated with: (2) crude kieserite containing NaCl; (3) kainite; (5) mixed MgSO4.H2O, KCl and NaCl; (6) mixed langbeinite and sodium sulphate.  In Example (7) Florida phosphate and kieserite are added to a melt of CaSO4 and K2SO4 at the same rate as magnesium phosphate, K2SO4 and CaSO4 are withdrawn.  The products can be used as mixed fertilizers.

Abstract: 1398536 Winding webs BELOIT CORP 18 Aug 1972 [2 Sept 1971] 38692/72 Heading B8R In a method of, and apparatus for winding a continuously supplied web W into rolls, a loop 139, Fig. 6, is formed in the web running to a full roll 130 and is fed into the nip N, between a new spool 58 and a driven reel drum 10, the new spool 58 having a perforated circumference and being supplied with sub-atmospheric pressure to facilitate nipping and attachment of the web thereto. A winding spool 29, Fig. 1, is urged against the rotating drum 10 by a roller 99 on a two armed lever 88, the web W being fed over the drum to the spool. A new, perforated spool 58 is held by brackets 28 on arms 16, the brackets sliding down the arms until the spool engages a track 31 which is adjusted so as to hold the spool clear of the drum 10. The perforated circumferential shell (72), Fig. 2 (not shown), of the new spool has hollow journals (56) at each end, the journals each rotatably carrying a bearing housing (62) against which, pneumatic seals (41), connected to a vacuum pump (54), abut. When spool 29 is full, the arm 88 is moved anticlockwise to retract the roller 99 and urge an arm 100 against the spool which is thus moved along a rail 122 and out of contact with drum 10. The arms 16 pivot so that the new spool moves along the track 31 to the winding position in contact with the rotating drum 10. As spool 29 slows down the web loop 139 forms and is eventually nipped with the aid of the suction applied to new spool 58. The web then breaks and starts winding on to the new spool.

Abstract: 989,444. Semi-conductor devices. RADIO CORPORATION OF AMERICA. Oct. 12, 1962 [Oct. 24, 1961], No. 38799/62. Heading H1K. A method of providing an electrical contact to a semi-conductor wafer comprises placing the wafer on a metallic plate, utilizing an electron beam to drill a hole through the wafer and partly through the plate so as to melt a portion of the plate whereby the molten portion rises within the hole and thereafter cooling the assembly so that the molten portion solidifies within the hole and makes rectifying or ohmic connection with the wafer. The plate and wafer may then be heated to a temperature below the melting point of either so as to alloy the portion of metal to the wafer or the wafer may be separated from the plate before the heating step occurs. In the latter case a sheet of insulating material, e.g. mica, ceramic, cellophane or other insulating resin or plastic, may be positioned between the wafer and plate to facilitate removal of the wafer from the plate. The process may be repeated using metal plates of differing conductivity types whereby ohmic and rectifying connections can be made to the wafer. The latter may be intrinsic or degenerately doped. The electron beam should have a diameter of between 0À5 and 3 mils, the average energy of the electrons in the beam should be about 10<SP>5</SP> Á and it should preferably be pulsed, e.g. 5 to 50 Ásecs. on, 50-100 Ásecs. off. A printed circuit board 43 carrying an etched copper circuit 45 is located between a wafer 41 and a metal plate 40 and an electron beam is used to form two holes which intersect portions of the circuit 45 and which finally contain solidified portions of metal 48, 48<SP>1</SP>. The metal plate is removed from the board and wafer and the arrangement is then heated whereby the volume of the portions 48, 48<SP>1</SP> is somewhat reduced (Fig. 4e). Thereafter electrodes 15, 25 may be evaporated through a mask on to the surface of the wafer. Either of electrodes 15, 25 or 48, 48<SP>1</SP> may make rectifying or ohmic contact with the wafer. In a solid circuit (Fig. 5a) comprising a five input diode OR gate, the above processes are used to provide ohmic contacts 58 to 58<SP>1111</SP> and rectifying contacts 68 to 68<SP>1111</SP> to a wafer 51, one surface of which is completely covered with insulating material 52 on to which conducting paths 78 to 78<SP>1111</SP>, e.g. of Ag or Pa and conducting strips 54 and 56 have been deposited. The semi-conductor may comprise Ge, Si, Ge-Si alloy, the phosphides, antimonides or arsenides of Al, Ga or In or the sulphides, selenides or tellurides of Zn or Cd. The metal plates may consist of Pb, Sn, A1, Zn, Cu or Te which may be doped or alloyed with Sb, As, In or Ga. Embodiments which utilize some of the possible combinations of the above materials are described in the Specification.
